Synchronizing arrangement utilizing an electromechanical resonator to derive clock pulses from a binary data signal

Claim 1

A COMMUNICATION SYNCHRONIZER FOR RECEIVED BINARY SIGNALS HAVING A BIT INTERVAL DETERMINED BY A NOMINAL TRANSITION FREQUENCY COMPRISING MEANS FOR PRODUCING DRIVE PULSES OF PREDETERMINED PHASE FROM EACH BINARY TRANSISTION OF SAID SIGNALS, AN ELECTROMECHANICAL RESONATOR DRIVEN BY SAID DRIVE PULSES, SAID RESONATOR BEING TUNED TO SAID NOMINAL TRANSITION FREQUENCY OF SAID BINARY SIGNALS, MEANS FOR DERIVING AN OUTPUT SIGNAL INDUCED BY THE VIBRATIONS OF SAID RESONATOR, MEANS FOR OBTAINING A COMPARISON WAVEFORM FROM SAID OUTPUT SIGNAL, MEANS FOR SELECTING AN INTERMEDIATE POINT ON SAID COMPARISON WAVEFORM AND PRODUCING A CLOCK PULSE IN FIXED TIME RELATION TO SAID IMMEDIATE POINT, AND MEANS RESPONSIVE TO THE POSITION OF SAID INTERMEDIATE POINT AND SAID DATA TRANSITIONS FOR ADJUSTING THE POSITION OF SAID INTERMEDIATE POINT TO BE MIDWAY BEWAY BETWEEN SAID TRANSISTORS.
